Aquatec PSW340-00 Tank Pressure Shut Off Switch 3/8" QC for Aquatec Booster Pumps

Aquatec PSW340-00 Tank Pressure Shut Off Switch 3/8" QC for Aquatec Booster Pumps

Aquatec PSW Series – Tank Pressure Sensing Switches

• Designed for in-line mounting near the hydropneumatic product water tank

• Automatically shuts off the booster pump when the tank is full

• Normally closed switch – factory pre-set at various shut-off pressures

• Ensures reliable operation of the hydraulic shut-off valve in typical under-counter RO systems

• Compatible with 1/4" or 3/8" tubing via built-in John Guest half cartridges
  

• For systems using both a permeate pump and a 6800 or 8800 series booster pump, or when shut-off pressure is above 40 PSI, an electronic shut-off valve (ESO) must be installed

  • Without an ESO at higher pressures, the system will not shut off properly and will continue running

Tip: Choose a shut-off switch based on your desired tank fill pressure.

Key Features:

• Inexpensive and compact design

• High reliability for consistent performance

• 100% factory tested

• Integrated John Guest half cartridges for easy installation
